For the general well being of the Internet I think any provider offering 1Gb/sec upload speeds to residential users needs to do deep packet inspection or employ some other method to protect against malware driven attacks. You can do some real harm with 1Gb/sec. DPI would probably be preferred since it could snoop out known attacks and allow the customer to utilize their upstream speeds legitimately. A blanket QoS policy for high usage is easier but has some obvious downsides. Probably not a bad idea at the 50-100Mbit/sec range either. There's too much malware out there to be oblivious to the risks.
